COKE-OVEN DOOR.

BPECIFICATION forming part of Letters Patent N0, 294,845, dated March11, 1884.

I Application filed December 1S, 1853. (No model) To in whom it mayconcern:

Be it known that we, XVALTER A. BLYTHE and J AMES HENDERSON, citizens ofthe United States, residing at Dunbar, in the county of Fayette andState of Pennsylvania, have invented certain new and useful Improvementsin Coke-Oven Doors; and we do declare the fol-.

lowing to be a full, clear, and'exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, andto the letters and figures of reference marked thereon,which form a partof this specification.

Our invention relates to improvements in coke-oven doors; and itconsists in the construction, combination, and arrangement of theseveral parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a front elevation of a coke-oven with thedoor in place. Fig. 2 is a front view of the oven with the door moved to"one side. Fig. 3 is a plan View of the door. Fig. 4 is a sectional viewon line 00 m, Fig. 1 Figs. 5 and 6 show a modifica tion, all of whichwill be described.

The oven A is provided with the doorway A, which, after the oven ischarged, is walled up, as at B, nearly to the top of the doorway,leaving the usual draft-opening, B. The door 0 is adapted to fit in thedoorway, with its upper end flush with the upper end of the wall, B.This door, it willbe seen, prevents the air from getting to the wall B,and therefore retains the heat in the oven. However, where the doorsimply fits in the doorway, it is nec essary to mortar up each side ofthe door with loam, so as to prevent air from getting be tween thejoints. To obviate the use of this loam altogetheig-we provide the doorwith flanges C, which extend laterally from the opposite sides of thedoor along the walls of the oven. These flanges, it will be seen, form atight joint, and keep the air from the wall B, and hence do away withthe necessity of the loam at the sides, as will be readily understood. I

In order to regulate the supply of air to the oven through opening B,weprovide the slide.- valve D,held in slides on the upper outer face ofthe door.. XVe prefer to hold this valve as shown high temperature,giving better in Figs. 3 and 6, in which the opposite sides of'the valveslide in slots formed between the upper ends of the flanges and thedoors. They are also guided by a strip, D, held at its lower end to thedoor, and having its upper end extended up over the valve, as shown. Aclamping-screw, D", turns through the bar D and bears against the valve,holding the same at any point desired. This valve is adjustablevertically to entirely close or vary the size of the draft-opening B" atwill. The valve being held firmlyin guides, there is no danger of itsbeing displaced by the forceof the draft of the oven. It is providedwith lugs or handles D",

so that it may be conveniently and easily operated.

By use of the door as above described good results are had, as will beunderstood from Figs; 5 and 6 and the above description; but in practicewe prefer to use the construction which we will now describe, as therebybetter results will be had, as will be'presently set forth.

To prevent the heat of the wall from burning the door, we form thelatter with a water chamber or jacket, E, which we keep filled withwater, so that no scorching or burning of the door will take place. okeep this jacket filled with water in the manner presently described.This chamber extends the full width and height of the door. A fine orair-passage, F, is formed in the door and close to the forward wall ofthe water-chamber. This flue extends'into the water-chamber, and itsback and sidesare subject to the heating action of the water in saidchamber. At the lower end this flue opens through the forward .plate ofthe door, forming the air-inlet F. This inlet is regulated and may beclosed by the valve G, which is held similarly to valve D, and may beclamped at any suitable point a desired by means of screw G, turningthrough strap or-bar G". In operation, the upper valve, D, may beclosed, so as to shut out direct draft through opening B. Then, byopening valve i, the air can pass through inlet F, thence through flueF, into the opening B. Inits passage through flue F the air is heatedand by time it enters opening B has reached a results, as is well knownin the art.

pipe, I, depends from the pipe II, and is proreadily removed from andapplied to the oven wit-h an air chamber or passage having an in- Asupportingrod, II, is arranged above the doorway, and eitends slightlyto each side of same. It is preferably made hollow, and 0011- I nectedby pipe II with the water-supply. A

vided with the stop-cock I. An elbow, 1 is swiveled on lower end of pipeI. This elbow may be turned, as shown in Fig. 4-, to deliver water intothejaeket E, or maybe turned out away from over said jacket, as will bereadily understood. A hanger, .I, is provided on its upper end with aneye, J, placed and movable laterally on the rod II. The opposite end ofthis hanger may be secured directly to the door, but is preferablyswiveled to upper end of the rod K, which, in connection with horizontalbail K, serves as a handle whereby to move the door.

here the door is made without the waterjacket and vertical tlue orairpassage, we sometimes dispense with bail K and use only rod K and a.vertical bail arranged below said rod K, as will beseen in Fig. 5. Yeprefer, however, to use bail Ii, as shown in Figs. 1, 2, 3, and c.

\Vhen desired to remove the door, it is tilted out, as indicated indotted lines, Fig. l, and then moved laterally to one side, as shown inFig. 2. Then it will be seen the weight of the door is taken off theoperator, and it may be at will.

Having thus described our invention, what we claim, and desire to secureby Letters Iateat, is-

.l. The door for eolce ovens, provided with lateral flanges, andprovided on its upper edge with a verticallyadjustable valve,substantially as set forth.

2. In a eolceoven having its doorway walled nearly to its upper end, thedoor herein doseribed, fitted to said doorway and having its upper endconstructed to tit flush with the up per end of the doorway-wall, andprovided let at its outer lower edge and 'an air-exit at its upper side,a valve adjustable over the air- 5 inlet, and slide-valve adj ustablevertically from the upper side of the door, all. arranged and operatingsubstantially as and for the purposes set forth.
